Description

457 935 Skärdelen 10 är vid sin från skaftet 12 vända ände 13 försedd med åtminstone en skärande egg, vilken ges olika utformning alltefter användningsområde. Sålunda är skäreggen eller skäreggarna raka och parallella med skärdelens längsgående centrumaxel när det år fråga om en pínnfräs medan skäreggarna är církelformiga när det är fråga om en radiefräs. Uppräkningen är endast exemplífierande och skärdelens 10 främre ände visas ej i detalj i fig 1 och 2, eftersom den kan variera på màngahanda sätt och ej utgör någon väsentlig del av föreliggande uppfinning. 457 935 The cutting part 10 is provided at its end 13 facing away from the shaft 12 with at least one cutting edge, which is given a different design depending on the area of use. Thus, the cutting edge or cutting edges are straight and parallel to the longitudinal center axis of the cutting part in the case of a pin cutter, while the cutting edges are circular in the case of a radius cutter. The enumeration is exemplary only and the front end of the cutting member 10 is not shown in detail in Figures 1 and 2, as it may vary in many ways and does not form an essential part of the present invention.

Vid sin mot skaftet 12 vända ände är skârdelen försedd med ett första koniskt parti 14, vilket är försett med ett första ingreppsorgan 15, vilket i det visade utföringsexemplet innefattar en första klack 16 samt en första urtagning 17.At its end facing the shaft 12, the cutting part is provided with a first conical portion 14, which is provided with a first engaging member 15, which in the embodiment shown comprises a first lug 16 and a first recess 17.

I fig 3 visas skärdelen 10 mer i detalj och sedd i papperets plan i fig 1 och 2. Därvid framgår att skärdelens 10 fria I ände 13 är försedd med ett nyckelgre pp 32, vars användning förklaras nedan.Fig. 3 shows the cutting part 10 in more detail and seen in the plane of the paper in Figs. 1 and 2. It appears that the free end 13 of the cutting part 10 is provided with a key handle pp 32, the use of which is explained below.

Låsskruven 11 uppvisar vid sin mot skârdelen vända ände ett andra koniskt parti, vilket är försett med ett andra ingreppsorgan 19, vilket är avsett att samverka med det första ingreppsorganet 15, Såsom framgår av fig 1 och 2 innebär anordnandet av det andra ingreppsorganet 19 att en väsentlig del av det andra koniska partiet 18 har avlägsnats. Det andra ingreppsorganet 19 innefattar en andra klack 20 samt en andra urtagning 21. I verksamt läge samverkar den första klacken 16 med den andra urtagningen 21 och den andra klacken 20 med den första urtagningen 17.The locking screw 11 has at its end facing the cutting part a second conical portion, which is provided with a second engaging member 19, which is intended to cooperate with the first engaging member 15. As can be seen from Figs. 1 and 2, the arrangement of the second engaging member 19 means that a substantial portion of the second conical portion 18 has been removed. The second engaging member 19 comprises a second lug 20 and a second recess 21. In the operative position, the first lug 16 cooperates with the second recess 21 and the second lug 20 with the first recess 17.

Innanför det andra ingreppsorganet 18, i axiell led, uppvisar lásskruven 11 ett utvändigt gängat, företrädesvis cylindriskt parti 22. Ett ínsexnyckelgrepp 23 är anordnat vid làsskruvens 11 innersta ände, varigenom lossning eller 457 935 åtdragning av làsskruven 11 möjliggöres genom skaftets 12 invändiga kanal 24. Normalt sker dock àtdragning eller lossning av lässkruven genom det yttre nyckelgreppet 32.Inside the second engaging member 18, in axial direction, the locking screw 11 has an externally threaded, preferably cylindrical portion 22. An Allen key handle 23 is arranged at the innermost end of the locking screw 11, whereby loosening or tightening of the locking screw 11 of the locking screw 11 is made possible. Normally, however, the locking screw is tightened or loosened by the external key grip 32.

Skaftet 12 är vid sin mot skärdelen 10 vända ände försedd med ett koniskt säte 25, vilket upptar de första och andra koniska partierna 14 och 18 hos skärdelen 10 resp làsskruven 11. Innanför det koniska sätet 25 uppvisar skaftet 12 ett i huvudsak cylindriskt, invändigt gängat parti 26, vilket samverkar med det utvändigt gängade partiet 22 på lásskruven 11. Innanför partiet 26 befinner sig den ovannämnda kanalen 24.The shaft 12 is provided at its end facing the cutting part 10 with a conical seat 25, which receives the first and second conical portions 14 and 18 of the cutting part 10 and the locking screw 11, respectively. Inside the conical seat 25, the shaft 12 has a substantially cylindrical, internally threaded portion 26, which cooperates with the externally threaded portion 22 of the locking screw 11. Inside the portion 26 is the above-mentioned channel 24.

I fig 1 visas utgångsläget för montering av skärdelen 10 i skaftet 12. I detta läge är làsskruven 11 förskjuten í axiell led mot det koniska sätets 25 öppna ände, varigenom möjliggöres att delens 10 första ingreppsorgan 15 föres in i det koniska sätet 25 och automatiskt intar ett läge för samverkan med det andra ingreppsorganet 19 hos làsskruven 11. vid rotation av skärdelen 10 i pilens 27 riktning, företrädesvis genom en nyckel som år i ingrepp med nyckelgreppet 32, kommer låsskruven 11 likaså att rotera i pilens 27 riktning. Samverkan mellan den utvändiga gängan 22 och den invändiga gängan 26 medför att låsskruven 11 och därvid även skärdelen 10 förskjutes axiellt in i skaftet 12 till dess att det konformiga partiet 14 kommer till anliggning mot det koniska sätet 25, dvs läget enligt fig 2 har uppnåtts. Skärdelen 10 är nu på ett fullgott sätt förankrad i skaftet 12.Fig. 1 shows the initial position for mounting the cutting part 10 in the shaft 12. In this position the locking screw 11 is displaced in axial direction towards the open end of the conical seat 25, thereby enabling the first engaging means 15 of the part 10 to be inserted into the conical seat 25 and automatically engage a position for co-operation with the second engaging member 19 of the locking screw 11. when rotating the cutting part 10 in the direction of the arrow 27, preferably by a key which is in engagement with the key grip 32, the locking screw 11 will also rotate in the direction of the arrow 27. The interaction between the external thread 22 and the internal thread 26 means that the locking screw 11 and thereby also the cutting part 10 is displaced axially into the shaft 12 until the conical portion 14 comes into abutment against the conical seat 25, ie the position according to Fig. 2 has been reached. The cutting part 10 is now fully anchored in the shaft 12.

I detta sammanhang skall påpekas att gängan 22 på låsskruven 11 tjänar två syften, nämligen dels att placera skärdelen 10 i ett fixerat läge i skaftet vid montering, dels att vid användningen av det skärande verktyget alltid säkerställa att skärdelen 10 hàlls kvar i'sitt fixerade läge oberoende av hur skärdelens 10 och skaftets 12 dimensioner påverkas av vid bearbetníngen utvecklad värme. 457 935 Gângorna 22 och 26 är utförda som högergângor vid högerskârande verktyg och som vänstergängor vid vânsterskärande verktyg.In this context, it should be pointed out that the thread 22 on the locking screw 11 serves two purposes, namely to place the cutting part 10 in a fixed position in the shaft during assembly, and partly to always ensure that the cutting part 10 is kept in its fixed position when using the cutting tool. regardless of how the dimensions of the cutting part 10 and the shaft 12 are affected by heat developed during machining. 457 935 The threads 22 and 26 are designed as right-hand threads for right-handed tools and as left-hand threads for left-handed cutting tools.

När skärdelen 10 skall bytas ut förfares pä omvänt sätt som vid monteringen, dvs rotation av skârdelen 10 i motsatt riktning mot pilen 27 sker till dess att lä get enligt fig 1 uppnås, varvid skärdelen 10 kan avlägsnas från skaftet 12.When the cutting part 10 is to be replaced, the procedure is reversed as in the assembly, ie rotation of the cutting part 10 in the opposite direction to the arrow 27 takes place until the position according to Fig. 1 is reached, whereby the cutting part 10 can be removed from the shaft 12.

Vid den i fig 4 visade utföringsformen har det från skärdelen 10a utgående koniska partiet 14a en relativt sett mindre axiell utsträckning, varvid det koniska partiet l4a övergår i ett cylindriskt pa rti 28 som vid sin fria ände uppbär ett första ingreppsorgan 15a, i form av ett laxstjärtformat utspràng, vilket är symmetriskt med avseende på skârdelens lOa rotationsaxel.In the embodiment shown in Fig. 4, the conical portion 14a emanating from the cutting part 10a has a relatively smaller axial extent, the conical portion 14a merging into a cylindrical portion 28 which at its free end carries a first engaging member 15a, in the form of a salmontail-shaped projection, which is symmetrical with respect to the axis of rotation 10a of the cutting part.

Làeekruven iia enligt fig 4:a: försedd med ett, mot skärdelen 10a vänt, cylindriskt parti 29, vilket uppvisar ett andra ingreppsorgan l8a i form av en 1 axstjârtformad urtagning, vilken är avsedd att upptaga ingreppsorganet 15a, varvid samverkan sker mellan ingreppsorganen 15a och l8a för överförande av rotationsrörelse samt krafter i axiell led.The locking screw iia according to Fig. 4: a: provided with a cylindrical portion 29 facing the cutting part 10a, which has a second engaging member 18a in the form of an ax-shaped recess, which is intended to receive the engaging member 15a, the engagement between the engaging members 15a and l8a for transmitting rotational motion and axial forces.

Vid sin från skärdelen loa vända ände är lásskruven lla försedd med ett utvändigt gängat parti 22a.At its end facing away from the cutting part 10a, the locking screw 11a is provided with an externally threaded portion 22a.

Skaftet 12a är försett med ett koniskt säte 25a för upptagande av det komiska partiet 14a. sätet 25a är skaftet försett med en cyl som i verksamt läge upptar partiet 29.The shaft 12a is provided with a conical seat 25a for receiving the comic portion 14a. seat 25a, the shaft is provided with a cyl which in operative position receives the portion 29.

Innanför det koniska indrisk urtagning 30 Den cylindriska urtagningen 30 övergår vid sin inre ände i en invändigt gängad urtagning 26a, vilken i verksamt läge samverkar med det utvändigt gängade partiet 22a.Inside the conical inner recess 30 The cylindrical recess 30 merges at its inner end into an internally threaded recess 26a, which in operative position cooperates with the externally threaded portion 22a.

Principiellt fungerar utföringsformen enligt fig 4 pà 457 935 motsvarande sätt som den ovan beskrivna utföríngsformen enligt fig 1 och 2.In principle, the embodiment according to Fig. 4 operates in a manner corresponding to the above-described embodiment according to Figs. 1 and 2.

Den i fig 5 schematiskt visade utföringsformen av uppfinningen har ett från skärdelen lOb utgående koniskt parti 14b, vilket vid sin inre ände är försett med en urtagning 31, i vilken en làsskruv llb med ett utvändigt gängat parti 22b är fastlödd.The embodiment of the invention schematically shown in Fig. 5 has a conical portion 14b emanating from the cutting part 10b, which at its inner end is provided with a recess 31, in which a locking screw 11b with an externally threaded portion 22b is soldered.

Skaftet 12b uppvisar ett koniskt säte 25b, vilket i verksamt läge upptar det koniska partiet 14b. Dessutom år skaftet l2b försett med en invändigt gängad urtagning 26b, vilken i verksamt läge upptar det utvändigt gängade partiet 22b.The shaft 12b has a conical seat 25b, which in operative position receives the conical portion 14b. In addition, the shaft 12b is provided with an internally threaded recess 26b, which in the operative position receives the externally threaded portion 22b.

Utföringsformen enligt fíg 5 skiljer sig således från de ovan beskrivna utföringsformerna genom att ingreppsorganen för överförande av rotationsrörelse samt axiella krafter har utelämnats. Vid utbyte av skärdelen l0b sä bytes även lásskruven llb.The embodiment according to Fig. 5 thus differs from the embodiments described above in that the engaging means for transmitting rotational movement and axial forces have been omitted. When replacing the cutting part l0b, the locking screw llb is also replaced.

Inom ramen för uppfinningen kan man även tänka sig att utföringsformen enligt fig 5 modifieras sä att gángförbandet mellan lásskruv och skärdel är belägen i urtagningen 31 medan lásskruven llb är fastlödd i skaftet l2b.Within the scope of the invention, it is also conceivable that the embodiment according to Fig. 5 is modified so that the threaded connection between locking screw and cutting part is located in the recess 31 while the locking screw 11b is soldered in the shaft 12b.

Utföringsformen enligt fig 6 påminner i mycket stor utsträckning om utföringsformen enligt fig 5. Den enda principiella skillnaden är att det utvändigt gängade partiet 22c är utförd i ett stycke med det koniska partiet 14c.The embodiment according to Fig. 6 is very similar to the embodiment according to Fig. 5. The only fundamental difference is that the externally threaded portion 22c is made in one piece with the conical portion 14c.

För samtliga ovan beskrivna utföringsformer bör konvinkeln för skärdelen och sätet understiga 25°. Dessutom skall påpekas att de ovan beskrivna utföringsformerna hänför sig till fräsar, dvs verktyg som roterar runt sin längsgående centrumaxel. Fräsar med små skärspetsar torde vara det dominerande användningsområdet för föreliggande uppfinning även om både borr- och svarvverktyg likaså faller inom ramen 457 935 för uppfinningen.For all the embodiments described above, the cone angle of the cutting part and the seat should be less than 25 °. In addition, it should be pointed out that the embodiments described above relate to cutters, ie tools that rotate around their longitudinal center axis. Cutters with small cutting tips should be the predominant area of use for the present invention, although both drilling and turning tools also fall within the scope of the invention.

Uppfinningen är pâ intet sätt begränsad till de ovan neskrivna utföringsformerna utan kan fritt varieras inom ramen för de efterföljande patentkraven.The invention is in no way limited to the embodiments described above but can be freely varied within the scope of the appended claims.
